The one-time No. 1 golfer in the world, Woods is still battling back from back surgery that he had on March 31. He missed the Masters and U.S. Open and was not a factor in the British Open or PGA Championships.

"I'd like to thank Sean for his help as my coach and for his friendship," Woods said on tigerwoods.com. "Sean is one of the outstanding coaches in golf today, and I know he will continue to be successful with the players working with him. With my next tournament not until my World Challenge event at Isleworth in Orlando, this is the right time to end our professional relationship."

Said Foley in a statement: "My time spent with Tiger is one of the highlights of my career so far, and I am appreciative of the many experiences we shared together," Foley said. "It was a lifelong ambition of mine to teach the best player of all time in our sport. I am both grateful for the things we had the opportunity to learn from one another, as well as the enduring friendship we have built. I have nothing but respect and admiration for him."
